Hello from Central Illinois! I am just getting started doing the research on building a motorized bike. To be honest what I have come across so far has just managed to confuse me more. Because this is a just for the fun of doing it project I am on a limited budget around $500.00...and am not sure what I can do on this budget. I've seen bikes for under $200 and engine kits out there for $150 or so but I get the impression that they are pretty much low quality and/or Chinese made junk. I am really hoping that with the help of this forum I can build a reasonably priced and fun to ride bike in time for the spring thaw.
